Measuring Departure from Diagonals-Parameter Symmetry for Ordinal Square Contingency Tables
For ordinal square contingency tables, Tomizawa et al. considered the measure to representÂ the degree of departure from the diagonals-parameter symmetry model. This measure attainsÂ the maximum value when one of probabilities for any two symmetric cells with respect to the mainÂ diagonal in the table is zero. The present paper proposes an improved measure which can attain theÂ maximum value even when the probabilities are not zeros.
